Application Circuit and Block Diagram 3.3 SPI 1.) Three signals control the serial peripheral interface of the BGT24MR2: SI (Data); CLK (Clock); CS (Chip select) 2.) The data bits SI (MSB first) are read in the shift register with falling edge of the CLK signal. Please make sure, that the data is present at least 10 ns before and at least 10 ns after the falling edge of the clock signal. 3.) The CLK and CS signals are combined internally. At least 20 ns before first rising edge of the first CLK signal CS needs to be in "low" state. While the Data is read, CS has to remain in "low" state. 4.) When Data read in is finished, the shift register content will be written in the latch at the rising edge of the CS signal. The time between the last falling edge of the CLK signal and the rising edge of the CS must be at least 20 ns.
